This study applied Testlet-based response theory (TRT) model to a set of reading comprehension data from a TOEIC practice test. The parameter estimates and test information were compared to those of the standard item response theory (IRT) model. The results show that the model choice could have a serious effect on item slope and guessing parameter estimates. However, the two models did not yield any significant difference in item difficulty and proficiency parameter estimates. Test information as a measure of global precision shows that the two models could yield a differential degree of test precision depending on the range of ability distribution. A further textual analysis was also performed to see why certain testlets have more dependence than others in the same test
